W-ELT-ROUNDIVNG TOOL.

SPECIFICATION forming part of Letters Patent No. 355,758, dated January11, 1887.

Application filed August 31, 1885. Serial No. 175,721. (No model.)

.To all whom it may concern.-

Be it known that I, EDWARD DAWSON, a citizen of the United States, and aresident of the city of Brooklyn, in the county of Kings and State ofNew York, have invented a new and useful elt-Rounding Tool, of which thefollowing is a specification.

The object of my invention is to provide a tool for rounding or paringwelts.

Referring to the accompanying drawings, Figure 1 shows a cross-sectionof a partly-finished shoe near the toe. Fig. 2 isa top view of the same.

At A is shown the upper, at B is shown the insole, andat a the welt, ashowing the line of stitches which secure the insole b, the upper, andthe welt ('2 together.

The purpose of my tool is to round or pare the welt 0 so that it is evenin width.

In Fig. 2, a shows the p'ared edge of the welt, with the cut portion 0projecting from the toe of the shoe. It will be seen that by the use ofmy tool the vertical edge of the welt c is trimmed by cutting from itall around the shoe a strip, 0 and that in this way the uneven edge 0 istrimmed off and an even smooth edge, 0, is left, so that the shoe is inproper condition to have the welt c sewed to the outer sole of the shoe.

The rounding of the welt, which my .tool is adapted for, must not beconfounded with the beveling or paring of the top of the welt. For thispurpose tools such as are shown in Patents Nos. 157,678, 157 ,947,233,190, and 240,154 may advantageously be used.

I believe myself to be the inventor, broadly, of a welt-rounding tool inwhich there is combined a cutting-knife, a gage'to determine the widthof the welt, and a holder adjacent to the rangement of mechanicaldetail, but claim this combination of parts when arranged and adapted toround or pare the vertical edge of a shoe-welt.

In the accompanying drawings'l ha'veshown' some of the best methods ofcarrying out my invention in practice, though other arrange- 5o mentsmay be adopted.

Fig. 3 shows a top'view, Fig.4 shows a bot tom view, Fig. 5 shows an endView, Fig. 6 shows a back View, Fig. 7 shows a front view,

and Figs. 8 to 16 show detailed views, of a 5 welt-rounder made inaccordance with my invention. F p

D is the handle of .the tool.

thereof.

E is the head F is the knife, having a cutting portion, f. 6

This knife is secured in position by the plate G and screw 9. This plateis clearly seen in Figs. 11, 13, and 15, where itis shown detached fromthe, tool. It is provided with a lip, 9

which embraces the knife F and holds it in 6 position. The plate Gforces the knife against two lugs, e, which project from the body of thetool E and into recesses, in which the front portion of the knife F isreceived, as at e. In front of the knife is a presser-foot, H, whichholds the leather in advance of the cutting-edge of the knife betweenits under surin the tool head, and which passes through a 8 square holein the lower lug e, the upper portion of this presser-foot terminatingin a cylindrical threaded portion, if, the upper portion of whichisprovided with a nut, t, by means the top of the square portion h atthe lower end and the upper lug e at the upper end, the pressure of theholder or presser-foot upon the welt can be regulated. The guide K has aguiding-surface, k, which enters the crease 0 formed by the upper andthe welt, and thus the knife F is forced to round the welt parallel withthe upper. To regulate this distance, the guide K is made adjustable bymeans of the screw m, which, working in slot m of the 5 guide-plate K,enables the said plate to be adof which and the spring t", which bearsupon justed to suit the width of welt which it is desired to cut. Theguide-plate K is recessed, as at n, on its upper surface, so that thepoint of the knife F lies below the shoulder formed 5 by the recess. Theoperation of the tool is exceedingly simple. Theknife being sharpenedand clamped in place, the guide-plate K is adjusted so that theproperwidth of welt will be cut. The welt is then passed in between thepresser-foot or holder H and the upper surface of the guide plate K, andthe tool is moved around the shoe, cutting a chip, as shown in Fig. 2,the knife doing the cutting, the presser-foot and guide-plate holdingthe welt against the strain of the knife, and the guide-plate serving toinsure an even rounding or paring of the welt. The welts of shoes areusually thin and flexible, and are often made still more flexible bybeing wet, and they cannot be out unless they are held adjacent to theedge of the knife, and preferably in front thereof, between surfacesadapted to hold and give sufficient stiffness to the flexible welt. Ifthis is not done, the cutting will be uneven and irregular.

Figs. 17, 18, 19, 20, 21, 22, 23, and 24 show a modification of myinvention. Dis the handle, *as before illustrated in the other figures.E is the body of the tool. K is the guideplate, having its guiding-edgeat k, as shown by letter in Fig. 22. The presser-foot H,with itsadjusting-nut, spring, and square portion, is the same as in thepreviously-described tool, as are the lugs e, which carry thepresser-foot. 5 The guide-plate K is made adjustable in the same way.The knife F, however, is arranged slightly in a different relation. Its{cuttingedge is shown at f, Fig. 19, and the knife is held in positionbetween a slot, 0, in the head 0 E and either one of the three slots 0 oo", 1 shown in the top of the guide-plate K. Thus the guide-plate may beadjusted for welts of three widths, and the knife will beheld inposition by the clamping action of the guide- 5 plate forcing the knifebetween the surface of one of its slots 0 o 0 and the slot 0 in the headof the tool. The guide-plate is held and adjusted in this modificationas in the previous form of tool shown and described. The projecting partof the knife is not shown in Fig. 18. Figs. 25, 26,27, 28, 29, 30, and31 show still another modificatiomin which Dis the handle of the tool, Ethe head thereof, Fthe knife, held by a guiding and clamping plate, K,hav- 5 5 ing three slots in it, 0 o 0 for permitting the guide-plate tobe adjusted for different widths of welt. The knife being held and theguideplate being adjustable, as in the last modification, no specialdescription is necessary. The

resser-foot or holder, however,'in this case consists of a roller, L,held in a suitable holder,

1), which has a squaredportion passing through the lug e, projectingfrom the head E of the tool, and a circular portion upon which a spring,R, can bear, which spring can haveits therein.

tension properly adjusted by a setscrew, z. In this modification it willbe seen a rolling presser-foot or holder is substituted for one whichslides over the leather.

In all the modifications, however, will be found the knife, thepresser-foot or holder adjacent to the edge thereof, and preferablymoving in advance of the cutting-edge of the knife,

a surface against which the presser or holder can force the welt, and aguide, preferably adjustable, to determine the width of the welt afterthe trimming operation.

In all the modifications the operation is substantiallythe same. Theshape of the presserfoot can be varied so that it will embrace the edgeof the knife, or it might be divided and lie on each side of thecutting-edge; but I prefer to have it advance in the movement of thetool in front of the cutting-edge, so that the welt will be firmly andsecurely held in front of such cutting-edge.

I am aware of the United States Letters Patent granted to Vrooman, No.141,406,- July 29, 1873, and I do not claim anything shown I am alsoaware of the patent granted to Barton, No. 186,524, January 23,1877, andI do not claim anything shown or described therein.

I reserve to myself the right to claim in another application thedetails of the several modified forms of tools herein shown.

What I claim, and desire to secure by Letters Patent, is

1. A welt rounding or paring tool consisting of a knife, a presser-footadjacent to the knife for holding the said welt, and a gage forregulating the amount cut from the welt, all arranged substantially asdescribed.
